Application Abreviews Notes
Flow Cyt Use 1µg for 106 cells.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.

ELISA 1/10000.
WB Use a concentration of 5 - 10 µg/ml. Predicted molecular weight: 32.8 kDa.
IHC-P Use a concentration of 5 - 10 µg/ml.
IHC-Fr Use a concentration of 5 - 10 µg/ml.
Inhibition Assay Use at an assay dependent concentration. This antibody will inhibit the activity of human or rat heme oxygenase 1.


  • Function
    Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase. Under physiological conditions, the activity of heme oxygenase is highest in the spleen, where senescent erythrocytes are sequestrated and destroyed.
  • Sequence similarities
    Belongs to the heme oxygenase family.
  • Cellular localization
    Microsome. Endoplasmic reticulum.

  • Overlay histogram showing HEK293 cells stained with ab12220 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab12220, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
